Hi Tim,

Thanks for posting!

I understand that the client Windows XP Home cannot install certificate to
enable a VPN connection. If I have misunderstood your concerns, please feel
free to let me know.

Based on my research, it could be related to the permission of following
folder.

I have asked the user to look for the machinekeys folder but she can only
find C:\WINDOWS\SYSTEM32\Microsoft\Crypto\RSA. Is this correct? She does
not log on to a network so therefore she does not have a profile so I
presume this is correct. Will the certificate want to install to a profile
path?

Yes, the certificate may want to install to a profile path. The
C:\Documents and Settings\All Users\Application Data folder is a hidden
folder. Please help your user know how to display them as the following:
